AMD Ryzen Threadripper PRO 9985WX vs AMD Ryzen Threadripper PRO 7995WX
Both are 64-core, 128-thread sTR5 workstation chips with 8 memory channels and 2TB ECC RDIMM support. The 9985WX is the newer Zen 5 part: higher clocks (3.2/5.4 GHz vs 2.5/5.1 GHz), faster memory (6400 vs 5200 MT/s) and PCIe 5.0 with 148 lanes. The 7995WX is Zen 4 and typically sells for less. Latest prices: the 9985WX was $7,799.00 on 2026-11-03. Buy the 9985WX for the fastest single-thread and memory-bound work; buy the 7995WX if you find it meaningfully cheaper and mostly run fully parallel renders or simulations.

What reviewers say
AMD Ryzen Threadripper PRO 7995WX
Owners treat the 7995WX as a render-farm and simulation part, praising its multithreaded throughput and memory capacity. Complaints center on platform cost, heat and the need for serious cooling.
- Multithreaded performancePraisedOwners report large gains in rendering, encoding and simulation versus fewer-core parts.
- Memory capacityPraised8-channel DDR5 with ECC and up to 2TB suits large datasets and many VMs.
- PriceCriticisedBuyers say the CPU plus sTR5 board and memory makes the total platform very costly.
Questions and answers
- Which is better for 3D rendering?
- Both have 64 cores, so fully parallel renders finish in similar time. The 9985WX has faster cores and memory, so it edges ahead on mixed scenes and simulation.
- Is the 9985WX worth the extra money?
- Only if you need its higher clocks, DDR5-6400 or the extra PCIe lanes. If the 7995WX costs much less and your work is purely multi-core, the savings are real.
- Do they use the same motherboard?
- Yes. Both are sTR5 chips, so they fit the same Threadripper PRO workstation boards and 8-channel DDR5 RDIMM setups.
- Which runs cooler?
- Both are rated 350W TDP and neither ships with a cooler. Plan on a strong liquid or large air cooler for either.
- Can either game?
- Yes, but neither has integrated graphics, so you need a discrete GPU. High clocks make the 9985WX the better of the two for gaming.
- How much memory can they take?
- Both support up to 2TB of ECC DDR5 RDIMM across 8 channels. The 9985WX runs that memory up to 6400 MT/s; the 7995WX up to 5200 MT/s.
